ASUS Intros Radeon HD 6870 DirectCu Graphics Card

ASUS rolled out its second AMD Radeon HD 6870 graphics card, and its first non-reference design one: the HD 6870 DirectCu. The card features two features that make it supposedly better than the reference design, the Direct Cu GPU cooler, and a refined PCB design that make use of high-grade components. To begin with, the DirectCu GPU cooler combines a GPU base in which copper heatpipes make direct contact with the GPU die, conveing heat to a dense aluminum fin array which is cooled by a quiet fan.

The PCB makes use of "Super Alloy" voltage regulation components, such as Super Alloy chokes, Super Alloy capacitors, and Super Alloy MOSFETs, that not only increase durability, but also result in a cooler operation. The card is also factory-overclocked slightly, with the GPU running at 915 MHz but memory staying at 4200 MHz GDDR5 effective. Display connectivity includes two DVI, and one each of DisplayPort and HDMI. Other features include Super Hybrid Engine (which manages clock speeds based on load), and Voltage Tweak (which allows adjustment of voltages). ASUS' new card is yet to be priced.

they are very big heatpipes

I like the power circuits of this card. "Super Alloy" components Looks good and it even has a little fuse:).

It's all about efficiency of the entire system, not really the number.

For instance, I can put 30 heatpipes on that card, all I'm going to do is lose surface area for the fin array.

As also noted, size of the heatpipes.

Doesn't seem very easy to replace if it's burned out. :ohwell:

So does anyone know what makes super alloy better than regular alloy or super duper alloy or how about my favorite gimmick alloy

i guess thats pretty enough since heatpipes for processor is start from 4 heatpipes, direct touch will give better performance to carry the heat off from the chip so the bigger size too ;)

I didn't say these components are better than others and there was no need to quote me on that:shadedshu, Also weird names:laugh: of components doesnt mean it's gimmick. Diamond chokes of Sapphire:respect:. But those chokes could be more quality than usual stuff and they could last longer than basic ones that fried and soldered out of my HD4850 for instance.

Glad to see they have the VRM area cooled with a heatsink.
